Abstract: A low-power power supply for an electronic circuit uses an existing current input and converts the current to a higher voltage sufficient for supplying an electronic circuit. The input current generates a defined input voltage, which input voltage is initially generated by voltage drop by the input current passing at least one diode in the open direction of the diode. The input voltage, through a transistor, charges a plurality of switched capacitor networks in a first mode of operation, and in a second mode of operation, the switched capacitor networks are coupled in series for multiplying the input voltage to second higher voltage that is supplied to a oscillating circuit. The oscillating circuit drives the input current via a transformer and half bridge driver to convert a low voltage current supply from a low voltage current into a low current and higher voltage useable for supplying a small electronic circuit.

Abstract: A system for galvanic isolation between an analog input signal and an analog output signal, which system performs an analog to digital conversion of the input signals into input digital data. As a result, input parameters can be corrected in a nearly perfect way.

The delta-sigma modulator (100) includes a bitstream converter (107) configured to generate a digital signal output substantially corresponding to an analog signal input, a periodicity detector (111) coupled to the bitstream converter (107) and configured to detect periodicity in the digital signal output, and a dithering sequence generator (116) connected to and activated by the periodicity detector (111). The dithering sequence generator (116) generates a dithering sequence. The delta-sigma modulator (100) further includes a pulse-width modulation (PWM) generator (119) coupled to the dithering sequence generator (116) and receiving the dithering sequence. The PWM generator (119) modulates the dithering sequence onto the analog signal input of the delta-sigma modulator (100) as a dithering signal.
